Abstract
A method and system are disclosed to reduce trace length and capacitance in a large memory footprint. When more dual in-line memory module (DIMM) connectors are used per memory channel, the overall bus bandwidth may be affected by trace length and trace capacitance. In order to reduce the overall trace length and trace capacitance, the system and method use a palm tree topology placement, i.e., back-to-back DIMM placement, to place surface mount technology (SMT) DIMM connectors (instead of through-hole connectors) back-to-back in a mirror fashion on each side of a printed circuit board (PCB). The system and method may improve signal propagation time when compared to the commonly used traditional topology placements in which all DIMM connectors are placed on one side of the PCB.
